Yacc: Yet Another Compiler-Compiler Stephen C. Johnson Computer program input generally has some structure; in fact, every computer program that does input can be thought of as defining an ``input language‘‘ which it accepts. An input language may be as complex as a programming language, or...
you will have encountered the mystical programs Lex & YACC, or as they are known to GNU/Linux users worldwide, Flex & Bison, where Flex is a Lex implementation by Vern Paxson and Bison the GNU version of YACC. We will call these programs Lex and YACC throughout - the newer versions ar...

TP Lex and Yacc are an independent development of the author and are freely available on the Internet. The system is widely used both for implementing Turbo Pascal applications which have to recognize nontrivial input formats and for teaching purposes in compiler construction courses.Graf...

用lex&yacc制作的计算器 资源简介 很多人都知道lex&yacc,特别是计算机科班毕业的。因为在unix上自带的bshell就有这些功能。 cygwin里面也有这些。 可是,这种基本的功能,在win32平台下,微软似乎忘了。 有个外国人写了个软件Parser Generator (bum-bee). 他把unix的这些功能,做了个软件放到win32平台上。 我的...
